HOW IT WORKS

This information is then used to calculate an acoustic cancellation signal, which is delivered through the vehicle’s speakers to reduce the targeted noise.

Microphones placed inside the cabin monitor residual noise levels, allowing the system to adapt the control signal for optimized performance over different road surfaces, while automatically adjusting over time as the vehicle ages.

At present, many car makers use thick insulation and customised tyres as a way to combat external noise, but Bose says these approaches are not only less effective but can increase the vehicle weight and reduce fuel efficiency.

The move is the company’s latest attempt to help bring down noise levels in vehicles.

Bose says the solution will be available to manufacturers whether or not they use their own in-car sound systems, with the first models to use QuietComfort RNC expected to be in production by the end of 2021.
